Available in PDF, EPUB and Kindle. Book excerpt: In this study, an overview is presented of agricultural policies on manure and minerals, relating to the Nitrate Directive to remedy excessive surface- and groundwater contamination from intensive agricultural practices. Six countries belonging to the European Union were studied: the Netherlands, Belgium, Denmark, France, Germany and the United Kingdom. The policies and their legal incorporation were related to agricultural and environmental conditions in each country. In addition, an inventory was made of agricultural mineral poli cies in the United States and Canada. Conditions for livestock farming in North America differ considerably from those in Europe, but their solutions shed a different light on European policies. Research has shown that there are still very considerable mineral surpluses in many countries and regions. In both the Netherlands and in the Flemish part of Belgium, existing problems due to very high levels of manure production are structural rather than local and cannot easily be solved by transport of manure to other regions. To a lesser extent. Germany, Denmark and relatively small parts of France (Brittany) and the United Kingdom, still exceed the norms for an equilibrium fertilization. In Denmark, existing problems can probably be solved within the existing legislative framework. The Netherlands, Flanders. several German Lander (Nordrhein-Westfalen and Schleswig-Holstein) and Brittany.

Download or read book Cycling of Mineral Nutrients in Agricultural Ecosystems written by M Frissel and published by Elsevier. This book was released on 2012-12-02 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cycling of Mineral Nutrients in Agricultural Ecosystems contains the papers presented in the first international environmental symposium of the Royal Netherlands Land Development Society held at Amsterdam on 1976. The symposium is cosponsored by the International Association for Ecology and Elsevier Scientific Publishing Company. This compilation reflects the exchange of information and ideas by specialists and participants of the symposium. The book is comprised of nine chapters, which cover the following concepts of nutrient cycling in agricultural ecosystems: principles and control of nutrient cycling; description and classification of agro-ecosystems; nutrient cycling data from different countries; and general discussion on nutrient balances, changes in soil pools, manipulations, and future researches. This book also offers potential background and perspectives for further studies on nutrient cycling in agro-ecosystems, presenting a view on what directions future research should take. This volume will be an invaluable reference source for environmental science students and professionals. Research workers in agriculture and other environmental disciplines will also find this book useful.

Download or read book Mineral Nutrition of Animals written by V. I. Georgievskii and published by Elsevier. This book was released on 2013-10-22 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mineral Nutrition of Animals reviews the research on the mineral nutrition of animals. This book explores the biological function and metabolism of minerals in the body, as well as mineral feeding of various species of farm animals. Topics range from water metabolism and mineral composition of feeds to the physiological role of macroelements such as calcium and potassium and microelements such as iron and copper. This text is comprised of 16 chapters; the first of which provides a historical overview of the science of mineral feeding of animals; mineral elements and their function in animal nutrition; and mineral feeding of animals under industrial conditions. The chapters that follow present general information on minerals, describe the link between biogeochemical regions and biochemical ecology, and analyze the factors affecting the mineral composition of animals' bodies. The reader is also introduced to water metabolism and the water requirements of animals; the metabolism of minerals absorbed into the digestive tract; and the kinetics of mineral metabolism in the blood, organs, and tissues. The next section is devoted to mineral feeding of various species of farm animals such as cattle, sheep, pigs, and poultry. This text concludes by looking at methods of controlling the adequacy of farm animals' mineral diet. This book will be of interest to students and practitioners in agriculture and food science.

This book was released on 2008-07-18 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of huge relevance in a number of fields, this is a survey of the different processes of soil clay mineral formation and the consequences of these processes concerning the soil ecosystem, especially plant and mineral. Two independent systems form soil materials. The first is the interaction of rocks and water, unstable minerals adjusting to surface conditions. The second is the interaction of the biosphere with clays in the upper parts of alteration profiles.
